Hello All,

I have a '77 280z and am looking for a vacuum hose schematic. I have downloaded the 77 shop manual and also the electronic fuel injection guide for the 280z but neither one has a schematic. For some reason that escapes me the previous owner had disconnected various hoses and I have no idea where they go. Thanks.

Check out the following link. This is the same diagram that's in the back of the 77 service manual...

This should help you out. I just re did all my vacuum lines under the hood of my Z and this schematic was real easy to follow.

If you're in need of a few feet of the vacuum line, let me know as I have about 5-6 extra feet of it. Not enough to do all the lines under the hood, but a few extra feet if you need hose to connect the vacuum bottle up the solenoids for example.

Thanks for the quick responses. I think that I can figure them out with these two diagrams.

You might also need this. Those other diagrams are for the vacuum lines in for the HVAC system. This one shows all the engine piping, vacuum lines fuel lines, etc. It's in the Engine Tune-Up section of the 77 FSM if my scan isn't clear enough.
